Generally, a download manager enables downloading of large files or multiples files in one session.
Many web browsers, such as Internet Explorer 9, include a download manager.
Stand-alone download managers also are available, including the Microsoft Download Manager.

if you do not have a download manager installed, and still want to download the file(s) you've chosen, please note:

You may not be able to download multiple files at the same time.
In this case, you will have to download the files individually.
(You would have the opportunity to download individual files on the "Thank you for downloading" page after completing your download.)

Files larger than 1 GB may take much longer to download and might not download correctly.

You might not be able to pause the active downloads or resume downloads that have failed.

The Microsoft Download Manager solves these potential problems.
It gives you the ability to download multiple files at one time and download large files quickly and reliably.
It also allows you to suspend active downloads and resume downloads that have failed.

SQL Server Compact 4.0 enables new scenarios and includes a host of new features, including the following:

SQL Server Compact 4.0 is the default database for Microsoft WebMatrix, which is a stack of web technologies for easily building and deploying websites on the Windows platform.

For enhanced development and debugging capabilities, including designer support, Visual Studio can be used to develop ASP.NET web applications and websites using SQL Server Compact 4.0.

Enabled to work in the medium or partial trust environments in the web servers, and can be easily deployed along with the website to the third party website hosting service providers.

Private deployment of SQL Server Compact further simplified by having all the required managed assemblies, and the x86 and x64 DLLs, including the Visual C++ 2008 runtime libraries (x86 and x64) SP1 in a single private folder in the install location of SQL Server Compact.

Stronger data security with the use of the SHA2 encryption algorithms for encrypting the databases.

T-SQL syntax enhancement by adding support for OFFSET and FETCH that can be used to write paging queries and new APIs like SqlCeConnection.GetSchema that provides the metadata information of the database.

Used with ADO.NET Entity Framework, SQL Server Compact now supports the columns that have server generated keys like identity, rowguid etc. and the code-first programming model.
